Abstract
Recently, the use of Carbon Fiber Reinforced Plastic (CFRP) composite, instead of metal materials, has increased in fields that have high demand for both lightweight and high specific strength materials, such as aircraft and automobile. Composites show different characteristics according to temperature and fiber array direction. Under the operating condition, the fuselage of an aircraft is often exposed to impacts from birds, hail etc. Therefore, Charpy impact fracture characteristics of the CFRP composite according temperature and fiber array direction need to be estimated to ensure aircraft safety. In this paper, after the Charpy impact tests, fractured surfaces were analyzed to estimate the impact fracture characteristics of the CFRP composite by SEM.
